This is the weakest PJ mount I have ever seen. There's no way to ever get it 100% tight. Even when fully unscrewed, the bracket wobbles. It's just terrible design. To be honest, I don't understand all the positive reviews. I bought it based on them, and I regret wasting my time and perforating my ceiling with this junk. Pajamas shake as people walk upstairs above the theater in the basement. (had no problems with my previous mount) Spend a little more and get something adjustable and stable.
